A MU-300 ACFT LOSES ELECTRICAL PWR; INTERRUPTING THE VOR AND GPS NAV SYSTEM WHICH CREATED A TEMPORARY CLASS B AIRSPACE INCURSION AT MCI; MO.

Narrative

AT APPROX XA20 CDT; I WAS OCCUPYING THE RIGHT SEAT WHILE ACTING AS PIC IN AN MU-300 ON CLIMB OUT FROM IXD; OLATHE; KS. WE DEPARTED VFR AND BEGAN A RIGHT TURN TO AVOID CLASS B AIRSPACE SURROUNDING KANSAS CITY WHEN WE LOST OUR NAV AIDS (BOTH VORS AND GPS) DUE TO WHAT WE NOW BELIEVE WAS AN ELECTRICAL PWR INTERRUPTION. WE CONTACTED KANSAS CITY DEPARTURE CTL AND WERE TOLD TO AVOID CLASS B AIRSPACE WHICH WE ATTEMPTED TO DO USING VISUAL REFERENCE SAID THE KANSAS CITY ; MO; AREA CHART. UPON LOSING OUR NAVAIDS; WE TURNED TO A HEADING OF 180 DEGS TO ENSURE WE WOULD NOT ENTER CLASS B AIRSPACE; BUT DUE TO THE CONFUSION SURROUNDING THE SUDDEN LOSS OF NAVIGATIONAL EQUIP; WE MAY HAVE DELAYED THE TURN ENOUGH TO HAVE INADVERTENTLY TOUCHED THE CLASS B BOUNDARY. USING VISUAL REFERENCES AND THE AREA CHART; WE DO NOT BELIEVE WE ENTERED CLASS B AIRSPACE; HOWEVER; IN THE MOMENTARY CONFUSION OF THE EVENTS; IT IS POSSIBLE WE MAY HAVE ENTERED IT BRIEFLY. THE LESSON HERE IS TO HAVE A PRE-DEP PLAN AND ANTICIPATE THE UNEXPECTED. WHILE I; THE PNF; HAD THE AREA CHART OUT AND WAS REFERENCING IT; NORMAL DEP DUTIES; COMBINED WITH A SUDDEN UNEXPECTED EVENT; COMBINED TO PRODUCE ENOUGH CONFUSION SO AS TO CAUSE DELAYED PLT ACTION WHICH RESULTED IN US DEVIATION FROM OUR PRE-DEP PLAN. THE OLD ADAGE APPLIES - FLY THE ACFT FIRST; TAKE CARE OF THE PROBLEM SECOND.
